Embodiment

[0019] Embodiment: a kind of air pressure forming process of carbon fiber product and glass fiber product, carry out according to the following steps:

[0020] ①. Pretreatment: Cut the fiber prepreg into the required size and shape, the fiber prepreg is one of carbon fiber prepreg and glass fiber prepreg, and then cut the prepreg according to the thickness requirements Several layers of fiber prepregs are stacked, and a release film is pasted on the surface of the stacked fiber prepregs. Pasting the release film can make the resin on the carbon fiber prepreg or glass fiber prepreg under high temperature and high pressure. It can be evenly leveled in the horizontal direction, which is beneficial to obtain smooth carbon fiber semi-finished products or glass fiber semi-finished products without pits and pinholes on the surface;

[0021] ②, air pressure molding: put the fiber prepreg stacked in step ① and coated with release film into the mold, and put the pressure block 2 on the ...

Abstract

The invention discloses an air pressure shaping technology of a carbon fiber product and a glass fiber product and a used die. The technology employs a briquetting in the shaping process, the briquetting can improve the precision of the product, and Using a booster pump and air pressure shaping enable uniform pressure in a mold cavity, resin on the carbon fiber pre-dip cloth or the glass fiber pre-dip cloth can flow stably under the high temperature and high pressure situation. Thereby a carbon fiber semi-finished product or a glass fiber semi-finished product with smooth surface which does not possess cavity and pin hole can be obtained, the difficulty for subsequent surface treatment can be reduced and the subsequent operation and time can be saved, the surface brightness and qualitative sense of the carbon fiber product and the glass fiber product can be enhanced. A die structure of the invention provides equipment support for the technology, so that the technology of the invention can be enforced.

Description

technical field [0001] The invention relates to a forming process of carbon fiber products and glass fiber products, in particular to a wind pressure forming process and a mold structure used in the process. Background technique [0002] The commonly used processing method of carbon fiber / glass fiber products is: slowly heat the formed carbon fiber / glass fiber prepreg to a certain temperature, keep it for 40-80 minutes, and then cool it naturally. The total molding time is at least 45 minutes. Moreover, during the high-temperature and high-pressure molding process, the epoxy resin on the surface of the carbon fiber / glass fiber cloth is affected by the high temperature, and it will undergo physical changes and flow slowly and be lost. Cavities will make the surface of carbon fiber / glass fiber semi-finished products quite unsightly, directly affecting the quality of carbon fiber / glass fiber products. Therefore, it is necessary to carry out surface treatment with paint to make...
